I got kicked from a UK server twice a couple of months ago for the same reason; for "wasting assets."
All I have to say is.... it just happens. You will get "WTF", "Play on a traning server" and "RTFM VBf2 noob" messages, but the squad leaders should call trans at their own risk.

Despite these drawbacks, I have had more fun than pain flying trans, and it is right now my favorite thing to do in PR. (I have told myself I have quit flying trans a million times, but I just come back eventualy.)
